Study Arms (2)

mechanical thrombectomy group

EXPERIMENTAL

Researchers can choose to deal with the stenosis or occlusion of blood vessels according to their own judgment, including stent thrombectomy, thrombus aspiration, balloon angioplasty, stent replacement, intra-arterial thrombolysis or various combinations of these methods.

Procedure: Mechanical thrombectomy

best medical management agroup

NO INTERVENTION

Best Medical Treatment and maximum supportive care according to local guidelines, not including mechanical thrombectomy, no intra-arterial treatment.

Interventions

Neurointerventionist determine whether to proceed with interventional therapy after assessing the location and degree of occlusion, the tortuosity of the access vessel, and the presence of stenosis or occlusion in the proximal artery. In cases where there is no proximal stenosis or occlusion, mechanical thrombectomy is performed, and the specific thrombectomy strategy is tailored by the researcher based on the patient's condition. For lesions associated with proximal vascular stenosis or occlusion, it is necessary to navigate the catheter through the proximal stenosis or occlusion to access the intracranial occlusion. Researchers have the discretion to treat the stenotic or occluded vessels, which may include options such as no treatment, stent thrombectomy, thrombus aspiration, balloon angioplasty, stent replacement, intra-arterial thrombolysis or various combinations of these methods.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Posterior circulation acute ischemic stroke within 24-72 hours from symptom onset/last seen well (except for isolated vertigo), where patient is ineligible for IV thrombolytic treatment or the treatment is contraindicated (e.g., patient presents beyond recommended time from symptom onset), or where patient has received IV thrombolytic therapy without recanalization.
  • Occlusion (TIMI 0-1) of the basilar artery or intracranial segments of both vertebral arteries (V4) as evidenced by CTA/MRA/DSA.
  • Age ≥18 and ≤ 80.
  • Baseline NIHSS score obtained prior to randomization must be equal or higher than 6 points.
  • No significant pre-stroke functional disability (mRS ≤ 1).
  • Patient treatable within 72 hours of symptom onset. Symptom onset is defined as the point in time the patient was last seen well (at baseline) if patients are unable to provide a reliable history or the point in time when symptoms have started if patients can provide a reliable history.
  • Informed consent obtained from patient or authorized patient surrogate

You may not qualify if:

  • Clinical criteria
  • Known hemorrhagic diathesis, coagulation factor deficiency, or oral anticoagulant therapy with INR \> 3.0.
  • Baseline platelet count \< 50000/µL.
  • Baseline blood glucose of \< 50mg/dL or \>400mg/dl.
  • Severe, sustained hypertension (SBP \> 220 mm Hg or DBP \> 110 mm Hg) NOTE: If the blood pressure can be successfully reduced and maintained below these levels using commonly used medications in China for these purposes (including iv antihypertensive drips), the patient can be enrolled.
  • Patients in whom baseline NIHSS can not be obtained by a neurologist or emergency physician prior to sedation or intubation.
  • Seizures at stroke onset which would preclude obtaining a baseline NIHSS.
  • Serious, advanced, or terminal illness with anticipated life expectancy of less than one year.
  • History of life threatening allergy (more than rash) to contrast medium.
  • Patients with acute stroke within the first 48 hours after percutaneous cardiac, cerebrovascular interventions and major surgery .
  • Renal insufficiency with creatinine ≥ 3 mg/dl.
  • Woman of childbearing potential who is known to be pregnant or lactating or who has a positive pregnancy test on admission.
  • Subject participating in a study involving an investigational drug or device that would impact this study.
  • Known diagnosis or clinical suspicion of cerebral vasculitis.
  • Patients with a pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations. This excludes patients who are severely demented, require constant assistance in a nursing home type setting or who live at home but are not fully independent in activities of daily living (toileting, dressing, eating, cooking and preparing meals, etc.).
